Preferably, the hair curler further includes a display panel and a button which are disposed at the bottom of the housing.

The hair curler provided by the present disclosure has the following beneficial effects.

1. The provided hair curler includes a housing and a curling device. The housing is configured to be held by a user. A chamber for receiving hair is defined in the housing. An opening communicated with the chamber is formed in the side, opposite to the side that matches a human hand, of the housing. The hair enters or leaves the chamber through the opening. The hair curling device is disposed in the chamber. In this design, the user can operate the hair curler only by holding the housing with a palm, and other handles do not need to be designed to help the user hold the hair curler, such that the size of the hair curler can be effectively reduced. Further, since the user can hold the hair curler with the palm for hair curling, the use is extremely convenient. The user only needs to hold the hair curler, to enable the opening to face the hair and to place the hair in the chamber of the hair curler through the opening for styling. After the hair is styled, the user holds the hair curler and pulls it down such that the styled hair leaves the chamber through the opening. With respect to a hair curler on which a handle is designed to assist in holding, the hair curler adopting this design is simple in structure and convenient to operate and is extremely humanized.

2. The housing includes a bottom region, an intermediate region and a top region. One side of the housing extends from the bottom region to the top region through the intermediate region in the form of a cambered surface. The opening is formed in an extending direction of the cambered surface. In this design, when the user needs to style the human hair close to the root portion by the hair curler, the hair curler is pressed against the skin of a human head. When the housing adopting the cambered design of the hair curler is in contact with the skin of the human head, owing to the smooth transition of the housing adopting the cambered design, the skin of the human head will not be scratched, and discomfort will not be caused. Thus, the user can gain a relatively better use experience. Meanwhile, the distance between the hair curling device of the hair curler and the root of the hair can be adjusted according to use requirements.

3. A wall surface of the chamber in the top region of the housing takes the shape of a cambered surface. In this design, the heated and styled hair can leave the chamber of the housing in a gradually expanding form. This design mode matches the fluffy status of the hair exiting the chamber of the housing, such that the hair can freely leave the chamber of the housing to keep its excellent curling style.

4. Two lugs that respectively match a human thumb and a human index finger are disposed in the top region of the housing and respectively disposed at two sides of the opening. In this design, when the user holds the housing, the two lugs can form two support points on the thumb and the index finger of the user, such that the user can hold the housing of the hair curler better and gain a relatively better holding experience.

5. The hair curling device includes a winding member and a hair hooking portion. The winding member is disposed in the chamber. The hair to be styled is wound around the winding member. The winding member includes a fixed end and a free end. The hair hooking portion is disposed on the winding member at a certain distance away from the fixed end in a direction from the fixed end to the free end. In this design, one segment of the hair from the hair hooking portion to the end portion of the hair can be uniformly wound around the winding member. The heated winding member can uniformly heat the segment of hair, such that the hair has an extremely excellent heating and styling effect on the whole.

6. The hair curling device further includes a first extending portion and a main body disposed at the fixed end of the winding member. The first extending portion is connected to the main body and extends toward the free end of the winding member to the hair hooking portion and is connected to the hair hooking portion. In this design, when the hair is wound around the winding member, the first extending portion presses and smooths the hair, such that the hair can be better attached onto the winding member. Thus, relatively better winding, heating and styling effects are achieved.

7. The hair curler further includes at least one second extending portion. A through hole is formed in the middle of the main body. The main body is sleeved on the winding member through the through hole. The first extending portion and the second extending portion are disposed at one end of the main body. In this design, when all the hair is wound around the winding member, the end portion of the free end of the hair can be well pressed on the winding member, such that the hair can be well attached onto the winding member on the whole.

8. The second extending portion extends for a relatively shorter distance than the first extending portion from the fixed end of the winding member to the free end of the winding member. In this design, not only can pressing and smoothing of hair by the second extending portion be guaranteed, but also winding of the hair by the first extending portion is facilitated.

9. The surfaces, close to an outer surface of the winding member, of the first extending portion and the second extending portion are 1 mm to 5 mm away from the outer surface of the winding member. In this design, the heating and styling effect on the hair from the winding member can be well controlled. By setting the distance between the surfaces, close to the outer surface of the winding member, of the first extending portion and the second extending portion and the outer surface of the winding member, when a hair layer is heated, a temperature difference between the portion, attached onto the winding member, of the hair layer and the portion, away from the surface of the surface of the winding member, of the hair layer will not be too large. Thus, the whole hair layer can achieve a relatively excellent heating and styling effect.

10. The hair curler further includes at least one friction member disposed on the winding member. The friction member is disposed on the winding member and can increase a frictional force between the hair and the winding member when the hair is wound around the winding member. Instead of moving on the winding member at random, the hair is uniformly wound on the winding member step by step. Thus, a relatively better winding effect is achieved.

11. The hair curler further includes a clamping device disposed in the chamber of the housing. The clamping device includes an open position and a closed position. In the open position, the hair leaves the chamber through the opening. In the closed position, the clamping device clamps one end of the hair. In this design, the clamping device clamps one end of the hair during winding and styling of the hair, such that the hair curling device can wind the hair relatively better. Further, since the clamping device clamps and fixes one end of the hair, no matter how the hair curler shakes, the hair in the chamber of the hair curler will not become loose, and neither heating nor styling of the hair will be affected. Thus, the hair can be styled relatively better. Further, since the clamping device clamps and fixes one end of the hair, the hair curler does not need to keep still during heating and styling of the hair. Therefore, the hair curler has relatively better operating performance.

12. An elastic member is disposed on each of the two clamping members. The elastic member is in contact with the winding member when the two clamping members are abutted against each other. Owing to the elastic member, the clamping device can clamp and fasten the hair relatively better and prevent the clamping device from damaging the hair.

13. The hair curler further includes a display panel and a button which are disposed at the bottom of the housing. In this design, neither the display panel nor the button will take up a holding region of the housing and affect holding and the overall beauty of the hair curler. Further, the user can conveniently display the use condition and parameter settings through the display panel so as to use the hair curler.

DETAILED DESCRIPTION

To make objectives, technical solutions and advantages of the present disclosure clearer, the present disclosure will be described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein merely serve to explain the present disclosure and are not intended to limit the present disclosure.

Referring to FIGS. 1 to 2, a first embodiment of the present disclosure provides a hair curler 20, which includes a housing 21, a hair curling device 10 and a clamping device 24. A chamber 22 is defined in the housing 21. The hair curling device 10 is disposed in the chamber 22 of the housing 21. An opening 23 communicated with the chamber 22 is formed in the housing 21. Hair to be styled enters the chamber 22 of the housing 21 through the opening 23 and is wound around the hair curling device 10. The clamping device 24 is disposed in the housing 21 and clamps and locates one end of the hair in the chamber 22 of the housing 21 to facilitate winding and styling of the hair on the hair curling device 10.

Referring to FIG. 3, the hair curling device 10 includes a driving mechanism 11, a hair hooking member 12 and a winding member 13. The hair hooking member 12 and the winding member 13 are connected to the driving mechanism 11. After the connection, the winding member 13 is still relative to the driving mechanism 11. The hair hooking member 12 is driven by the driving mechanism 11 to rotate relative to the winding member 13. While rotating relative to the winding member 13, the hair hooking member 12 hooks the hair and drags the hair to be wound around the winding member 13.

Referring to FIG. 4, the driving mechanism 11 includes a driver 111, a front cover 112, a rear cover 113 and a transmission member 114. The front cover 112 is connected to the driver 111. A connecting member 1121 is disposed in the middle of the surface, away from the driver 111, of the front cover 112 and configured to be connected to the winding member 13. The rear cover 113 and the front cover 112 are fastened and connected to form a receiving cavity. A through hole 1131 is formed in the middle of the rear cover 113. When the front cover 112 and the rear cover 113 are connected, the receiving cavity formed by the front cover 112 and the rear cover 113 is communicated with the outside through the through hole 1131. The connecting member 1121 passes through the through hole 1131 of the rear cover 113. The winding member 13 passes through the through hole 1131 of the rear cover 113 to be connected to the connecting member 1121. The transmission member 114 substantially takes the shape of a circular ring. A sleeving hole 1141 is formed in the middle of the transmission member 114. The transmission member 114 is sleeved on the connecting member 1121 through the sleeving hole 1141 and can rotate around the connecting member 1121. In the present embodiment, the driver 111 is a gear case including an output gear 1111. Gear teeth are formed at the periphery of one end surface of the transmission member 114 and cooperate with the output gear 1111 of the driver 111, such that the driver 111 drives the transmission member 114 to rotate around the connecting member 1121 through the output gear 1111.

Referring to FIGS. 5 to 6, the winding member 13 is cylindrical and includes a fixed end 132 and a free end 134. A fixing hole 133 is formed in the fixed end 132 of the winding member 13. The winding member 13 is fastened to the connecting member 1121 in the middle of the front cover 112 in a matching manner through the fixing hole 133 so as to be secured to the front cover 112.

Referring to FIG. 7, the hair curler 20 further includes a friction member 136. The winding member 13 includes an end cover 137. At least one slot 135 which is parallel to an extending direction of the winding member 13 and communicated with a surface of the winding member 13 is formed in the winding member 13. The friction member 136 passes through the slot 135. After that, the end cover 137 seals the winding member 13, such that the friction member 136 is clamped in the slot 125. There may be one, two or a plurality of slots 135. There also may be one, two or a plurality of friction members 136 to match the slots 135. Preferably, there are two slots 135 symmetrically disposed along the winding member 13, and there are two friction members 136 respectively passing through the slots 135. When the hair hooking member 12 hooks the hair and guides the hair to be wound around the winding member 13, the friction member 136 is configured to increase a frictional force between hair and the surface of the winding member 13, such that the hair can be uniformly attached onto the winding member 13. compared with a traditional winding member with a smooth surface, the hair will not slide on the winding member 13 at random to result in nonuniform winding when wound around the winding member 13. In this design, the hair can be uniformly wound around the winding member 13 to achieve an excellent winding effect. The friction member 136 may be a rubber strip, a strip-shaped brush or a strip-shaped felt. Understandably, the friction member 136 is not limited to the solution that the slot 137 is formed in the winding member 13 and the friction member 136 passes through the slot 137. It may also be configured such that no slot 137 is formed in the winding member 13, and the friction member 136 is attached onto the surface of the winding member 13, so long as the friction member 136 is disposed on the winding member 13 to increase the frictional force between the winding member 13 and the hair.

In the present embodiment, the winding member 13 is heatable. Through the winding member 13, the hair curler 20 heats and styles the hair 80 wound around the winding member 13. In some other embodiments, a heating element may be disposed on a wall surface, close to the chamber 22, of the housing 21 to heat the hair 80 wound around the winding member 13 for heating and styling.

Referring to FIGS. 8 to 10, the transmission member 114 includes a transmission segment 1142 and a connection segment 1143, which are connected through mechanical cooperation or are integrally formed, preferably, integrally formed. Gear teeth 1144 are formed on the end surface, away from the connection segment 1143, of the transmission segment 1142, and in particular, are circularly formed at the peripheral edge of the end surface, away from the connection segment 1143, of the transmission segment 1142. The driver 111 drives the transmission member 114 to rotate through cooperation between the output gear 1111 and the gear teeth 1144 on the transmission member 114. A plurality of bosses 1145 is circularly disposed on an end surface of the connection segment 1142. A plurality of slots 125 is circularly formed in the end surface of the end, connected to the transmission member 14, of the hair hooking member 12. The shapes, the sizes and the positions of the slots 125 match those of the bosses 1145. The transmission member 14 is connected to the hair hooking member 12 through cooperation between the bosses 1145 and the slots 125, such that the transmission member 114 that rotates drives the hair hooking member 12 to hook the hair. Understandably, the transmission member 14 is detachably connected to the hair hooking member 12 through cooperation between the bosses 1145 and the slots 125. Thus, the transmission member 14 and the hair hooking member 12 can be detached and replaced very conveniently.

Further, the driving mechanism 11 may not include the transmission member 114. Gear teeth may be formed at the end, which cooperates with the driver 111, of the hair hooking member 12, such that the driver 111 directly drives the hair hooking member 12 to rotate through cooperation between the output gear 1111 and the gear teeth of the hair hooking member 12.

Referring to FIG. 11, the hair hooking member 12 includes a main body 122, a first extending portion 123 a, a second extending portion 123 b and a hair hooking portion 124. The main body 122 is a cylindrical barrel with a hole formed in the middle. The hair hooking member 12 is sleeved on the winding member 13 through the hole formed in the middle of the main body 122. The slots 125 are formed in the main body 122. The hair hooking member 12 is connected to the transmission member 114 through the main body 122. The first extending portion 123 a and the second extending portion 123 b are circularly disposed at an end opposite to the end, which cooperates with the transmission member 114, of the main body 122. The first extending portion 123 a and the second extending portion 123 b are configured to press the hair when the hair hooking portion 124 hooks the hair to be wound around the winding member 13, such that the hair is well attached onto the winding member 13 and will not become loose. The first extending portion 123 a extends to be close to the free end 134 of the winding member 13 from the main body 122 and is connected to the hair hooking portion 124, such that the hair hooking portion 124 is located closely to the free end 134 of the winding member 13.

The second extending portion 123 b extends for a relatively shorter distance than the first extending portion 123 a from the main body 122 to the free end 134 of the winding member 13. There may be one, two or a plurality of, preferably two, second extending portions 123 b. The two second extending portions 123 b and the first extending portion 123 a are circularly disposed at the end, away from the driving mechanism 11, of the main body 122 at equal angles.

Understandably, beneficial effects can be achieved when the two second extending portions 123 b and the first extending portion 123 a are disposed on the main body 122 at equal angles. Thus, it can be guaranteed that when all the hair is wound around the winding member 13, the end portion at the free end of the hair can be well pressed onto the winding member 13. It can be understood that when the number of the second extending portions 123 b is too small, the end portion of the hair may warp and may not be attached onto the winding member 13 due to stress of the hair per se, resulting in a poor hair winding effect. Further, the warping hair cannot be heated or styled by the winding member 13, leading to a poor hair styling effect. Further, the second extending portion 123 b extends for a relatively shorter distance than the first extending portion 123 a from the fixed end 132 of the winding member 13 to the free end 134 of the winding member 13. That is, the second extending portion 123 b is relatively shorter than the first extending portion 123 a. In particular, the length of the second extending portion 123 b is one third or a half of the length of the first extending portion 123 a. Owing to this design, the second extending portion 123 b can press and smooth the end portion of the hair, and the first extending portion 123 a can wind up the hair conveniently. It can be understood that when the second extending portion 123 b and the first extending portion 123 a have the same length or the second extending portion 123 b extends to be close to the hair hooking portion 124, the second extending portion 123 b will hinder winding of the hair, which easily causes knotting of the hair and is unfavorable for successful winding of the hair around the winding member 13.

In some transformation embodiments of the present embodiment, the hair hooking portion 124 may be directly connected to the main body 122. At this time, instead of being disposed at the free end 134 of the winding member 13, the hair hooking portion 124 is located at the end, close to the driving mechanism 11, of the winding member 13. Understandably, the hair hooking portion 124 may also be disposed in any position relative to the winding member 13.

In some transformation embodiments of the present embodiment, the winding member 13 may also be driven by the driving mechanism to rotate. The hair hooking portion 124 is disposed on the winding member 13. The winding member 13 rotates to drive the hair hooking portion 124 to rotate so as to hook the hair. Thus, the hair is wound around the winding member 13.

Referring to FIGS. 12 to 13, it is defined that the hair 80 includes a fixed end 81 and a free end 82. The fixed end 81 refers to the end, connected to a human head, of the hair 80. The free end 82 refers to the end portion of the human hair. When the hair 80 is being wound by the hair curling device 10, the fixed end 81 of the hair 80 is clamped and located by the clamping device 24. The driving mechanism 11 drives the hair hooking portion 124 to rotate around the winding member 13. During rotation, the hair hooking portion 124 hooks the hair 80. The hair hooking portion 124 cooperates with the first extending portion 123 a to exert a force surrounding the winding member 13 onto the hair 80. Since the fixed end 81 of the hair 80 is clamped and located by the clamping device 24, one segment of the hair 80 from the fixed end 81 to the free end 82 is pulled toward the winding member 13 in a direction A shown in FIG. 12 under the action of the force formed by the hair hooking portion 124 and the first extending portion 123 a and is wholly wound around the winding member 13.

Referring to FIG. 12, FIG. 13, FIG. 14A and FIG. 14B, it should be noted that a hair hooking portion 103 of a traditional hair curler is disposed at a fixed end 1011 of a winding member 101. When the traditional hair curler winds the hair 80, the fixed end 81 of the hair 80 is blocked by a blocking member 103. After being hooked by the hair hooking portion 102 that rotates around the winding member 101, one segment of the hair 80 from the hair hooking portion 102 to the free end 82, namely L1 shown in FIG. 14A, is guided to a position A of the winding member 101 shown in FIG. 14B under the action of a force of the hair hooking portion 102 and is wholly wound in the position A of the winding member 101. This hair winding mode easily causes hair accumulation when the segment L1 of the hair 80 from the hair hooking portion 102 to the free end 82 is wholly wound in the position A of the winding member 101, leading to a poor winding effect. Further, since the hair 80 is accumulated in the position A of the winding member 101, when the winding member 101 heats and styles the hair wound around the winding member 101, the temperature of the hair 80 close to a surface of the winding member 101 is relatively higher. The temperature of other hair is relatively lower because it is accumulated and relatively farther from the surface of the winding member 101. That is, since the hair 80 is wound and accumulated in the position A of the winding member 101, the hair 80 is non-uniformly heated. Thus, the hair 80 has an extremely poor heating and styling effect, and is partially curled and partially not curled. At the same time, one segment of the hair from the fixed end to the free end cannot be substantially curled.

Referring to FIG. 12, FIG. 13, FIG. 15A and FIG. 15B, by contrast, the hair hooking portion 124 of the hair curler provided by the present disclosure is located at the free end 134 of the adjacent winding member 13. When the hair curler winds the hair 80, one segment of the hair from the fixed end 81 to the free end 82, namely, L2 shown in FIG. 15A, is uniformly wound from the free end 134 of the winding member 13 to the fixed end 132 of the winding member 13 step by step under cooperation between the hair hooking portion 124 and the first extending portion 123 a. Further, when the winding member 13 heats the hair, since the hair 80 is uniformly wound around the winding member 13, the heated winding member 13 can uniformly heat the whole segment of hair 80. Thus, the overall heating and styling effect of the hair 80 is extremely excellent. The segment of the hair 81 from the fixed end 81 to the free end 82 can be heated, wound and styled. Understandably, the hair hooking portion 124 of the hair curler provided by the present disclosure is not limited to being located at the free end 134 of the adjacent winding member 13 so long as a relatively better winding effect can be achieved by the fact that the hair hooking portion 124 is disposed at any distance away from the fixed end 132 of the winding member 13 in the direction from the fixed end 132 to the free end 134 of the winding member 13 rather than the fact that the conventional hair hooking portion is disposed at the fixed end of the winding member. Preferably, the hair hooking portion 124 is located in any position from the middle of the winding member 13 to the free end 134 of the winding member 13.

Further, a hair layer formed when the hair 80 is wound around the winding member 13 is located between an outer surface of the winding member 13 and surfaces, close to the winding member 13, of the first extending portion 123 a and the second extending portion 123 b. In this way, during rotation of the first extending portion 123 a and the second extending portion 123 b, the relatively fluffy hair 80 wound around the winding member 13 can be pressed and smoothed, such that the hair 80 is better attached onto the winding member 13. Thus, a relatively more favorable winding effect is achieved.

Further, owing to the first extending portion 123 a and the second extending portion 123 b, the hair curling device 10 can well control the thickness of the hair layer formed by winding the hair 80 around the surface of the winding member 13. That is, the thickness of the hair layer wound around the winding member 13 is limited by the distance between the surfaces, close to the outer surface of the winding member 13, of the first extending portion 123 a and the second extending portion 123 b and the outer surface of the winding member 13. In this design, the heating and styling effect on the hair 80 from the winding member 13 can be well controlled. By setting the distance between the surfaces, close to the outer surface of the winding member 13, of the first extending portion 123 a and the second extending portion 123 b and the outer surface of the winding member 13, when the hair layer is heated, a temperature difference between the portion, attached onto the winding member 13, of the hair layer and the portion, away from the surface of the surface of the winding member 13, of the hair layer will not be too large. Thus, the whole hair layer can achieve a relatively better heating and styling effect. Understandably, if the first extending portion 123 a or the second extending portion 123 b is not disposed to limit the thickness of the hair layer, when the hair layer is relatively thicker, the temperature difference between the portion, attached onto the surface of the winding member 13, of the hair layer and the portion, away from the surface of the surface of the winding member 13, of the hair layer will be relatively larger. As a result, when heating and styling of the hair close to the surface of the winding member 13 are accomplished, the hair away from the surface of the winding member 13 cannot be favorably heated or styled, or when heating and styling of the hair away from the surface of the winding member 13 are accomplished, the hair close to the surface of the winding member 13 is damaged by overheating. In particular, the surfaces, close to the surface of the winding member 13, of the first extending portion 123 a and the second extending portion 123 b are 1 mm to 5 mm, preferably 2 mm to 3 mm, away from the surface of the winding member 13.

Moreover, since the friction member 136 disposed on the winding member 13 can increase the frictional force between the hair 80 and the winding member 13 when the hair 80 is wound around the winding member 13, the hair 80 will not move at random on the winding member 13, and will be uniformly wound around the winding member 13 step by step. Thus, a relatively better winding effect is achieved.

Referring to FIGS. 16 to 20, the clamping device 24 is disposed in the chamber 22 of the housing 21. The clamping device 24 includes an open status and a closed status. In the open status, the hair 80 leaves the chamber 22 through the opening 23. In the closed status, the clamping device 24 clamps and fastens the hair 80 at the chamber 22 of the housing 21 to facilitate winding and styling of the hair.

The clamping device 24 includes two oppositely disposed clamping members 241, which include an open position and a closed position. In the open position, the two clamping members 241 are away from the chamber 22 of the housing 21 and are located inside the housing 21. In the closed position, the two clamping members 241 are abutted against each other at the chamber 22 of the housing 21 to clamp and fix the hair 80. Understandably, to facilitate winding of the hair 80, the two clamping members 241 are close to the free end 134 of the winding member 13 with respect to the hair hooking portion 124. Preferably, each clamping member 241 is provided with a semi-circular region 2417. When the two clamping members 241 are abutted against each other, the two semi-circular regions 2417 form a through hole. A region formed by the through hole right allows the winding member 13 to pass through. In this design, the two clamping members 241 and the winding member 13 cooperate to clamp the hair 80, such that the hair 80 is prevented from revolving when the hair hooking portion 124 pulls the hair 80 to be wound around the winding member 13. Further, the two clamping members 241 preferably clamp the free end 134 of the winding member 13 when abutted against each other.

It can be understood that the number of the clamping members 241 is not limited to two, and there may be a plurality of so long as the clamping members 242 include the open position and the closed position to clamp and release one end of the hair 80.

In some embodiments, an elastic member is disposed on each of the two clamping members 241. In particular, the elastic member may be but not limited to a spring. When the hair curler 20 is not in use, the two clamping members 241 are elastically offset in the housing 21 under the elastic action of the elastic member to be in the open position. When the hair curler 20 is in use, the clamping members 241 are pressed with the fingers of a user. The spring is compressed. The two clamping members 241 are abutted against each other in the chamber 22 of the housing 21 to be in the closed position.

In particular, a first end cover 211 and a second end cover 212 may be disposed inside the housing 21 and are fastened and connected to each other to form a receiving cavity. Each clamping member 241 includes a clamping portion 2412 and an extending portion 2413. The clamping portion 2412 is disposed in the receiving cavity formed by the first end cover 211 and the second end cover 212. The extending portion 2413 extends out of the receiving cavity formed by the first end cover 211 and the second end cover 212 through a notch 2121. Two fixing members 2414 are disposed on each clamping member 241. One spring 2415 is mounted on each of the two fixing members 2414. After that, the four springs 2414 disposed on the two clamping members 241 are arranged in an array of two lines and two rows. The second end cover 212 further includes a check ring 2122. The ends, away from the fixing members 2414, of the four springs 2415 are propped against the check ring 2122. The check ring 2122 is designed into a step 2123 in a middle region of the second end cover 212. A space formed by the step 2123 realizes that the check ring 2122 can be pressed against the spring 2414 and the clamping members 241 can move to the closed position of the clamping device 241 through the space formed by the step 2123. The second end cover 212 further includes four stand columns 2124. Four limiting slots 2416 are formed in corresponding positions of the clamping members 241. The stand columns 2124 are clamped in the limiting slots 2416 respectively. The stroke space of the clamping members 241 is limited by the stand columns 2124 and the abutted end surfaces of the clamping members 241.

In some other embodiments, the hair curler 20 may include a controller (not shown). A switch is disposed on the housing 21 of the hair curler 20. A driving member is disposed in the clamping device 24, is connected to the clamping device 24 and is configured to drive the clamping device 24 to be opened or closed. The switch and the driving member are electrically connected to the controller. The user controls the switch to transmit a control signal to the controller. Based on a signal transmitted by the switch, the controller controls the driving member to drive the clamping device to be opened or closed.

In some other embodiments, the switch can be designed as a pressure sensor. The user controls the opening and closing of the clamping device 24 based on the intensity of a force exerted onto the housing 21. In particular, the user can set a pressure threshold in the controller. When the user exerts pressure onto the housing 21, the pressure sensor detects the pressure exerted onto the housing 21 by the user and transmits detected pressure data to the controller. The controller compares the data transmitted by the pressure sensor with the threshold set inside the controller. When a pressure value transmitted by the pressure sensor is larger than the threshold set in the controller, the controller controls the driving member to drive the clamping device to be closed. When the pressure value transmitted by the pressure sensor is smaller than the threshold set in the controller, the controller controls the driving member to drive the clamping device to be opened.

Referring to FIG. 21, the clamping device 24 is configured to clamp the fixed end 81 of the hair when the hair 80 is styled by the hair curler 20. Compared with a traditional hair curler in which a blocking member 200 is disposed to prevent the hair 80 from revolving during winding, the hair curler provided by the present disclosure has remarkable beneficial effects since the clamping device 24 described above is provided. Although the traditional blocking member 200 can block one end of the hair 80 when the hair 80 is wound by the hair curling device to prevent the hair 80 from revolving and to facilitate winding of the hair 80, in the styling process of the hair 80, since the blocking member 200 only blocks one end of the hair 80 in a direction perpendicular to an extending direction of the hair 80 but it does not fix the hair in the direction perpendicular to the extending direction of the hair 80 or fix the hair 80 in the extending direction of the hair 80, during heating and styling of the hair 80, the traditional hair curler has to keep still. Once the hair curler shakes in the styling process, the hair 8 moves in the extending direction of the hair 80 or in the direction perpendicular to the extending direction of the hair, and the hair will become loose. As a result, the hair 80 cannot be well wound around the winding member 13, leading to a poor styling effect. Further, during actual use, to maintain a relatively better styling effect, the traditional hair curler has to keep still, leading to poor operating performance. By contrast, since the clamping device 14 provided by the present disclosure clamps the hair 80, the hair curler 20 has a relatively better winding effect on the hair 80 first. Further, no matter how the hair curler 20 shakes, it does not affect the styling of the hair 80. Thus, the hair 80 achieves a relatively better styling effect. Understandably, owing to no need of maintaining immobilization, the hair curler 20 has relatively better operating performance.

Further, in order to enable the clamping device 24 to clamp and fasten the hair 80 relatively better and to prevent the clamping device 24 from damaging the hair 80, the elastic member is disposed on the abutted surface of the two clamping members 241. When the two clamping members 241 are in the closed position, the elastic member is in contact with the winding member 13 and cooperates with the winding member 13 to clamp and fix one end of the hair 80. In particular, the elastic member may be a rubber strip or a PVC strip.

Referring to FIG. 22, in one embodiment of the present disclosure, the hair curling device 10 is started in a manner as below: when the clamping device 24 is in the closed status, that is, when the two clamping members 241 are in the closed position, the hair curling device 10 automatically starts to hook, wind and perm the hair 80. In particular, a circuit board 300 and the controller (not shown) are disposed inside the hair curler, and the circuit board 300, the controller and the driving mechanism 11 are electrically connected. Two Hall switches 301 are disposed on the circuit board 300. A magnet is disposed on each of the two clamping members 241. When the two clamping members 241 are in the closed position, the positions of the magnets disposed on the two clamping members 241 correspond to those of the Hall switches 301. Thus, when the two clamping members 241 are in the closed position, the magnets disposed on the clamping members 241 trigger the Hall switches 301. Based on signals transmitted by the Hall switches 301, the controller controls the driving mechanism 11 to run so as to wind, heat and style the hair 80.

Referring to FIG. 1, FIG. 3 and FIGS. 23 to 24, in the embodiment, the user holds the side opposite to the side, in which the opening 23 is formed, of the housing 21 to use the hair curler 20. The housing 21 includes a bottom region 211, an intermediate region 212 and a top region 213. One side of the housing 21 extends from the bottom region 211 to the top region 213 through the intermediate region 212 in the form of a cambered surface 214. When the hair curling device 10 is disposed in the chamber 22 of the housing 21, the driving mechanism 11 of the hair curling device 10 is located in the bottom region 211 of the housing 21. Correspondingly, the winding member 13 is located in the intermediate region 212 of the housing 21. The free end 134 of the winding member 13 is located at the joint of the intermediate region 212 and the top region 213 of the housing 21. The opening 23 is formed from the bottom region 211 of the housing 21 to the top region 213 of the housing 21 in an extending direction of the cambered surface 214 to form an arc-shaped opening. The formation of the arc-shaped opening matches the curling form of the hair placed at the opening, such that the user can easily place an entire wisp of hair into the chamber 22 of the housing 21 through the arc-shaped opening to facilitate winding of the hair. Thus, the hair curler 20 has relatively better operating performance. Further, in this design, when the user needs to style the human hair close to the root portion by the hair curler 20, the hair curler 20 is pressed against the skin of the human head. When the housing 21 adopting the cambered design of the hair curler is in contact with the skin of the human head, owing to the smooth transition of the housing adopting the cambered design, the skin of the human head will not be scratched, and discomfort will not be caused. Thus, the user can gain a relatively better use experience. Meanwhile, the distance between the hair curling device of the hair curler and the root of the hair can be adjusted according to use requirements. The opening 23 is defined by the bottom region 211, the intermediate region 212 and the top region 213 of the housing 21 into a bottom portion, an intermediate portion and a top portion. The slots formed in the bottom portion of the opening are configured to guide the entire wisp of hair when the hair is styled by the hair curler 20, such that the entire wisp of hair can conveniently enter the chamber 22 through the intermediate portion of the opening. The top portion of the opening is configured to allow the styled hair to leave the chamber 22 through the top portion of the opening. Preferably, the opening 23 has a larger extending caliber toward the top region 213. An objective of this design is that when the hair curler 20 is in use, the top region 213 of the housing 21 is close to the root portion of the human hair, the entire wisp of hair 80 to be styled is relatively fluffy at the root, and the relatively larger opening 23 in the top region 213 brings much convenience for the user to place the entire wisp of hair 80 into the opening 23, which facilitates hooking and curling by the hair hooking portion 124. Further, the top portion of the opening 23 in the top region 213 of the housing 21 is preferably designed in a way that the opening contour formed at the top portion of the opening 23 is larger than the free end 134 of the winding member 13. In this design, when the hair 80 is moved out of the chamber 22 from the top region of the opening 23 after being heated and styled on the winding member 13, the hair 80 will maintain the shape that is taken when wound around the winding member 13. Thus, an optimal curling and styling effect is maintained. It should be noted that as the heated and styled hair 80 has a relatively higher temperature, at this time, in case of being pulled by any obstacle, the styled hair 80 will be straightened to some extent when leaving the chamber 22. As a result, a relatively better curling and styling effect cannot be achieved. Understandably, owing to the arc-shaped opening, the hair curler 20 is more beautiful on the whole.

Further, a wall surface of the chamber 22 in the top region 213 of the housing 21 takes the shape of a cambered surface. In this design, the heated and styled hair can leave the chamber 22 of the housing 21 in a gradually expanding form. This design mode matches the fluffy status of the hair exiting the chamber 22 of the housing 21, such that the hair can freely leave the chamber 22 of the housing 21 to keep its excellent curling style.

Further, the winding member 13 is disposed inside the chamber 22 of the housing 21. Preferably, the free end 134 of the winding member 13 is located at the joint of the intermediate region 212 and the top region 213 of the housing 21. Compared with the traditional hair curler, this design mode has the advantage that instead of being located at the edge of the opening 23, the free end 134 of the winding member 13 is at a certain distance away from the opening edge of the top region 21 of the housing 21. Thus, when the hair 80 required to be wound and styled by the user is relatively closer to the human head, the distance between the free end 134 of the winding member 13 and the opening edge can effectively prevent the skin of the head from being scalded.

In some other embodiments, two lugs 215 that respectively match a human thumb and a human index finger are disposed in the top region 213 of the housing 21 and respectively disposed at two sides of the top portion of the opening 23. In this design, when the user holds the housing 21, the two lugs 215 can form two support points on the thumb and the index finger of the user, such that the user can hold the housing 21 of the hair curler 20 better and obtain a relatively better holding experience. Further, the two lugs 215 are elastically connected to the housing 21 and match the clamping members 241 and the extending portions 2413. The user can press the lugs 215 with the thumb and the index finger to drive the two clamping members 241 to the closed position. In this design, the user can operate the hair curler 20 very conveniently. The design conforms to the ergonomic principles better, such that the whole hair curler 20 is extremely convenient and comfortable for use. Further, the intermediate region 212 extends toward the top region 213 in a diffusing manner. That is, the further the housing 21 extends from the intermediate region 212 to the top region 213, the larger the contour region formed thereby is. The design has the following advantages: the user can hold the hair curler 20 better, the top region 213 that extends in a diffusing manner can well prevent the hair curler 20 from sliding down to avoid its sliding and breakage, and further, the user can gain a relatively better holding experience.

In some other embodiments, a flange 214 is disposed in the bottom region 211 of the housing 21. The flange 214 and the bottom region 211 of the housing 21 together restrain a holding region of a palm. The design has the following advantages: the bottom region 211 and the flange 214 can form compression on the human palm to clamp the human palm to a relatively lower degree; further, the hair curler 21 is less likely to shake after the user holds the hair curler 20 through the housing 21; and the user can hold the hair curler 20 more firmly.

In some other embodiments, in order to enable the user to hold the hair curler 20 better and more firmly, bulges or grains may be disposed on the contour of the outer surface of the housing 21 to increase a friction force between the surface of the human palm and the housing 21. Thus, the user can hold the hair curler 20 better.

In some other embodiments, a display panel and a button are disposed at the bottom of the hair curler 20. In this design, neither the display panel nor the button will take up the holding region of the housing 21 and affect holding and the overall beauty of the hair curler 20. Further, the user can conveniently display the use condition and parameter settings through the display panel so as to use the hair curler 20.

Referring to FIG. 25, when the hair curler 20 is in use, the user holds the housing 21 with one hand, arranges a wisp of hair 80 to be styled in order with the other hand, places the wisp of hair at the opening 23, and then presses the lugs 215 with fingers. The lugs 215 are compressed when pressed. Since the lugs 215 match the clamping device 24, the clamping device 24 is correspondingly driven to the closed position to clamp the fixed end 81 of the hair. After that, the hair curling device 10 is started to wind the hair 80. Since the fixed end 81 of the hair 80 is clamped and fixed by the clamping device 24, during winding of the hair 80, one segment of the hair from the fixed end 81 to the free end 82 is pulled step by step to move toward the free end 134 of the winding member 13 and is wholly wound around the hair curling device 10 at last. Then, the hair curler 20 is started to heat and style the hair. After heating and styling of the hair are finished, the clamping device 24 is released. The hair leaves the chamber 22 through the opening 23.

The hair curler 20 is designed such that the user can operate the hair curler 20 by holding the housing 21 with the palm. Other handles do not need to be designed to help the user hold the hair curler 20. Owing to this design, the size of the hair curler 20 can be effectively reduced, such that the hair curler 20 is relatively smaller. Further, the user holds the hair curler 20 with the palm to wind the hair. Thus, the use is extremely convenient and comfortable. The design conforms to the concept of ergonomic principles better. The user only needs to hold the hair curler 20 and enables the opening 23 to face the hair 80. The hair 80 is placed in the chamber 22 of the hair curler 20 through the opening 23 for styling. After the hair is styled, the user holds the hair curler 20 and pulls it down such that the styled hair leaves the chamber 22 through the opening 23. Compared with a hair curler on which a handle is designed to assist in holding, the hair curler adopting this design is simple in structure and convenient to operate and is extremely humanized. Further, since the clamping device 24 is configured for clamping, the hair curling device 10 achieves a relatively better winding effect on the hair 80. Thus, the styling effect of the hair 80 is relatively better.

Referring to FIG. 26, a second embodiment of the present disclosure provides a hair curler 30. A hair curling device 301 is disposed inside the hair curler 30. The hair curling device 301 and the hair curling device 10 described above adopt the same structure. The hair curler 30 further includes a housing 31 in which a chamber 32 is defined. A first opening 33 is formed in the housing 31. The hair 80 to be styled enters the chamber 32 through the first opening 33. The hair curling device 301 is disposed in the chamber 32. The hair curling device 301 includes a winding member 3011, which includes a free end 3012. A second opening 34 is formed in the housing 31 close to the free end 3012 of the winding member 3011. The styled hair 80 leaves the chamber 32 through the second opening 34.

In some other embodiments, the clamping device 24 described above is disposed on the hair curler 30 close to the second opening 34. The hair curler 30 further includes a first handle 35, a second handle 36 and a panel 37. The first handle 35 is connected to the housing 31. The second handle 36 is connected to the panel 37. The first handle 35 and the second handle 36 are pivotally connected. The user holds the first handle 35 and the second handle 36 to use the hair curler 30. The clamping device 24 is driven in a manner as below: when the first handle 35 and the second handle 36 are closed, the clamping device 24 is driven to the closed position to clamp the hair 80; and when the first handle 35 and the second handle 36 are opened, the clamping device 24 is driven to the open position, and the hair 80 leaves the chamber 32 through the second opening 34. Compared with a conventional hair curler employing a blocking member, owing to the clamping device 24, the hair curling device 301 can achieve a relatively better winding effect and styling effect. Thus, the hair curler 30 has relatively better operating performance on the whole.

Referring to FIG. 27, a third embodiment of the present disclosure provides a hair curler 40 with a hair curling device 401 disposed therein. The hair curling device 401 and the hair curling device 10 described above adopt the same structure. The hair curler 40 further includes a housing 41. A chamber 42 is defined in the housing 41 to receive the hair 80 to be styled. The hair curling device 401 is disposed in the chamber 42. A first opening 43 communicated with the chamber 42 is formed in the housing 41. The hair 80 to be styled enters the chamber 42 through the first opening 43. A second opening 44 communicated with the chamber 42 is further formed in the housing 41. The styled hair 80 leaves the chamber 42 through the second opening 44. The hair curling device 401 includes a winding member 4011, which includes a free end 4012. The second opening 44 is located close to the free end 4012 of the winding member 4011. The second opening 44, which is annular, is communicated with the first opening 43 and surrounds the free end 4012 of the winding member 4011. The design has the advantage that when leaving the chamber 42 through the second opening 44, the styled hair 80 can maintain a relatively better curvature.

Further, the hair curler 40 further includes the clamping device 24 described above. The clamping device 24 is disposed on the end surface where the second opening 44 is formed. The clamping device 24 clamps the fixed end 81 of the hair 80 when the hair is wound by the hair curling device 401. In this design, the hair 80 can be prevented from revolving when the hair 80 is wound by the hair curling device 401, such that a relatively better hair curling role is played. Further, the clamping device 24 fastens the hair 80 during heating and styling of the hair 80. When a traditional hair curler with only a blocking member shakes during heating and styling of the hair 80, the hair will become loose. However, in this design, the clamping device 24 clamps the hair 80, such that no matter how the hair curler 40 shakes during heating and styling of the hair 80, the hair 80 will not become loose. Thus, a relatively better styling effect is achieved.

Referring to FIG. 28, a fourth embodiment of the present disclosure provides a hair curler 50, which is different from the hair curler 40 in only that no clamping device 24 is disposed inside a housing 51 of the hair curler 50. Instead, a holding member 52 is disposed on the housing 51 and configured to cooperate with a hand of the user to enable the user to firmly hold the hair curler 50 through the holding member 52. This design has the following advantage: when the user firmly holds the hair curler 50, a thumb of the user can be free, such that when using the hair curler 50, the user can press the fixed end 81 of the hair 80 on an end surface 53 of the second opening 54 with the thumb to well wind the hair 80 around the hair curling device 10 for styling.

Referring to FIG. 29, in some other embodiments, a collecting region 56 may be disposed on the end surface 53 of the second opening 54.
